Abstract: A tissue roll holder includes a sucking member having a threaded rod connected to and extending upwardly from a central portion of a flexible disc body, an abutting plate disposed above the disc body and permitting extension of the threaded rod therethrough, and a mounting seat disposed on the abutting plate for mounting a tissue roll and having a threaded hole that engages the threaded rod. When a peripheral portion of the disc body is pressed by a peripheral abutting portion of the abutting plate and is attached sealingly to a supporting surface, the mounting seat is rotatable about the threaded rod relative to the abutting plate so as to move the threaded rod and the central portion of the disc body upwardly away from the supporting surface, thereby forming a vacant space between the central portion of the disc body and the supporting surface.

Abstract: A container assembly includes a cover cap mounted detachably and sealingly on a container. The cover cap has a pump-mounting wall portion defining a pump-receiving chamber, an inlet formed in the pump-mounting wall portion and in fluid communication with the pump-receiving chamber and a storing space of the container, and a valve-mounting wall portion defining an opening which is in fluid communication with the storing space and the atmosphere. A pump member is disposed movably and sealingly in the pump-receiving chamber, and has an outlet in fluid communication with the pump-receiving chamber and the atmosphere. An urging member urges the pump member away from the inlet. First and second check valves are respectively mounted on the cover cap and the pump member for closing the inlet and the outlet of the pump-receiving chamber, respectively. An air-inlet valve is mounted on the pump member for closing the opening in the cover cap, and is operable to uncover the opening in the cover cap.

Abstract: A lid for an air-tight container is composed of a base and a seal. The base has a circular groove defined in a bottom face thereof. The seal has a circular extension formed to correspond to the circular groove. When the circular extension is received in the circular groove, the engagement between the base and the seal is secured.
